5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your new blower motor. Follow these steps carefully:
5.1 Pre-Installation Checks
- Disconnect Power: Ensure all electrical power to the furnace or air handler unit is completely shut off at the circuit breaker. Verify with a voltage tester.
- Verify Compatibility: Confirm that the Packard 45117 motor is the correct replacement for your existing motor. Check model numbers and specifications.
- Required Capacitor: Obtain a 5MFD 370 VAC run capacitor if you do not already have one or if your existing capacitor is not compatible or is faulty. This motor requires an external run capacitor.
- Tools: Gather necessary tools, which may include screwdrivers, wrenches, wire strippers, electrical tape, and a multimeter.
5.2 Removal of Old Motor
- Carefully label all wires connected to the old motor and its capacitor before disconnecting them. Take photos for reference.
- Disconnect the old motor's wiring and capacitor.
- Remove the mounting hardware securing the old motor to the blower housing.
- Slide the old motor out of the blower wheel. Note the position and depth of the shaft within the blower wheel for proper alignment during new motor installation.
5.3 Installation of New Motor
- Mounting: Slide the new Packard 45117 motor into the blower wheel, ensuring the shaft is inserted to the correct depth as noted during removal. Secure the motor to the blower housing using the mounting studs and appropriate hardware. Ensure the motor is firmly seated and aligned.
- Wiring Connections: Refer to the connection diagram on the motor label (Image 4.1) and your labeled wires from the old motor. The Packard 45117 motor typically has the following wire colors for speed selection:
- White: Common (Line)
- Black: High Speed (Line)
- Blue: Medium Speed (Line)
- Red: Low Speed (Line)
- Brown/White & Brown: Capacitor connections
- Capacitor Connection: Connect the 5MFD 370 VAC capacitor to the brown and brown/white wires from the motor. Ensure the capacitor is securely mounted and its terminals are properly insulated.
- Final Checks: Double-check all wiring connections for tightness and correctness. Ensure no wires are pinched or obstructing moving parts. Manually spin the blower wheel to confirm it rotates freely without rubbing against the housing.
- Restore Power: Once all checks are complete, restore power to the furnace or air handler unit at the circuit breaker.

6. Operation
The Packard 45117 motor is designed for continuous operation within its specified parameters. Once installed and wired correctly, the motor will operate according to the signals from your furnace or air handler's control board, utilizing its 4-speed capabilities to provide appropriate airflow for heating or cooling cycles.
- The motor's speed is determined by which speed wire (Black, Blue, or Red) is energized by the control board.
- Ensure the furnace or air handler is set to the desired mode (Heat, Cool, Fan On) and temperature.
- Listen for smooth operation. Any unusual noises should be investigated immediately.
7. Maintenance
The Packard 45117 motor is designed for minimal maintenance. However, periodic checks can help ensure its longevity and efficient operation:
- Cleaning: Annually, or more frequently in dusty environments, disconnect power and inspect the motor and blower wheel for dust and debris accumulation. Clean with a soft brush or vacuum cleaner. Excessive dust can impede airflow and cause the motor to overheat.
- Bearings: This motor features sealed ball bearings, which do not require lubrication. Do not attempt to oil the bearings.
- Wiring Inspection: Periodically check all electrical connections for tightness and signs of wear or corrosion.
- Capacitor Check: If the motor experiences starting issues or runs sluggishly, have the run capacitor tested by a qualified technician.
8. Troubleshooting
Before performing any troubleshooting, ensure all power to the unit is disconnected.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start or hums but doesn't spin |
|
|
| Motor runs but airflow is weak |
|
|
| Motor is excessively noisy |
|
|
| Motor overheats and shuts off |
